American actor, improviser and writer who voices the Trill officer Ensign Barnes and the computer of the USS Cerritos in Star Trek: Lower Decks.
Jessica McKenna is an American actor, comedian and writer, known for the improvised musical podcast Off Book and for voice work in animation.
In Star Trek: Lower Decks she voices Ensign Barnes, a Trill member of the Cerritos crew. Barnes is introduced in the first episode, Second Contact, on a date with Rutherford that carries on cheerfully through a rage-virus outbreak, and she remains a familiar face on the bridge and in the bar for the rest of the series.
McKenna also provides the voice of the Cerritos computer and a variety of incidental characters.
